• A Device-to-Circuit Methodology for HCI-Induced Variability Study Featuring High Efficiency Test Array Incorparated with Physical Model

  2026-03-22

  article

  This work presents a unified framework for large-scale characterization and statistical modeling of hot-carrier-induced (HCI) variability in 55 nm CMOS technology. A 16 × 16 nMOSFET testing array enables high-throughput HCI evaluation, while a compact virtual-source model (VSM) is employed to extract and analyze key transport parameters. The study identifies the HCI-induced traps are the dominant physical mechanisms responsible for aggravated parameter variation after stress. The degradation statistics of multiple parameters can be well described by Exponential-Poisson distribution, and strong inter-parameter correlations are identified and modeled. A variation-aware aging model incorporating parameter correlation is development and implemented in Verilog-A for circuit-level reliability simulation. The proposed framework provides a systematic and efficient approach for investigating HCI-induced variability and supports reliability-aware circuit design.

• Synthesis of Pd–Ag Alloy Nanoframes Comprised of Hollow Ridges by Templating With Ag Nanocubes

  ChemNanoMat · 2026-04-01

  articleOpen access

  Noble‐metal nanoframes are attractive for catalytic applications due to their open structures and large specific surface areas. However, traditional nanoframes are known to suffer from poor structural robustness because of their ultrathin ridges. Here, we address this issue by developing a new class of nanoframes characterized by relatively thick but hollow ridges. Our demonstration is based upon Pd and a typical synthesis involves the one‐shot injection of PdBr 2 powder suspension into an aqueous mixture containing Ag nanocubes, ascorbic acid, poly(vinyl pyrrolidone), and KBr held at 75°C. The poor solubility of PdBr 2 in water enables slow release of Pd (II) and thus a steady reduction rate for controlling the deposition of Pd atoms. During the synthesis, the side faces of Ag nanocubes are continuously carved away through galvanic replacement, accompanied by the deposition of Pd atoms on the corners and edges for the generation of cage cubes—cubes with through holes across the opposite faces. At a later stage, the Ag remaining in the ridges is etched away, leading to the formation of hollow ridges with a final composition of Pd 1 Ag 2 . The Pd–Ag alloy nanoframes exhibited good structural robustness during 1 h of chronoamperometric test toward formic acid oxidation reaction.

• Super ‐Hydrophilic SAMs via Chlorine Substituted All‐Hydrophilic Molecule Modification for Monolithic Perovskite‐Silicon Tandem Solar Cells

  Advanced Energy Materials · 2025-09-15 · 9 citations

  article

  Abstract Self‐assembled monolayers (SAMs) have emerged as highly promising hole transport layers for inverted perovskite solar cells, owing to their low parasitic absorption and effective charge extraction. However, their inherent strong hydrophobicity often inhibits the quality and uniformity of perovskite films and induces defects at the buried interface. In this study, a chlorine‐substituted all‐hydrophilic molecule is introduced to modify the buried interface. Such decoration transforms the hydrophobic SAM into a super‐hydrophilic surface, significantly enhancing the quality and uniformity of perovskite films. This chlorine‐substituted molecule exhibits a strong coordination with lead ions and effectively passivates defects at the buried interface of perovskite films. As a result, the single‐junction wide‐bandgap (1.67 eV) perovskite solar cell achieves a power conversion efficiency of 23.97%, the highest value achieved for MeO‐2PACz‐based devices. Furthermore, the perovskite‐silicon tandem solar cell reaches an efficiency of 31.12%. Additionally, the applicability of chlorine‐functionalized all‐hydrophilic molecule at the buried interface modification is demonstrated to various SAMs (4PADCB, 2PACz and Me‐4PACz) and narrower‐ or wider‐bandgap (1.61, 1.68, and 1.72 eV) perovskite solar cells. This work presents a promising strategy to overcome the challenges associated with SAM‐based perovskite solar cells, paving the way for further performance advancement.

• Parallel Imaging Using Virtual Conjugate Coils and Spatial Nulling Maps (VCC-SNMs)

  Proceedings on CD-ROM - International Society for Magnetic Resonance in Medicine. Scientific Meeting and Exhibition/Proceedings of the International Society for Magnetic Resonance in Medicine, Scientific Meeting and Exhibition · 2025-09-16

  article

  Motivation: One of the key challenges in parallel imaging (PI) reconstruction is the amplification of noise. Effectively minimizing the noise is essential for achieving high-quality images. Goal(s): Implementation of highly robust and efficient PI reconstruction method with reduced noise amplification. Approach: The recent SNMs method has shown its robustness and efficiency as one hybrid-domain PI reconstruction method. Phase constraint was incorporated in the SNMs method by employing virtual conjugate coils (VCC-SNMs). Results: The VCC-SNMs method was successfully developed in the study, and it was shown to be effective in achieving less amplified noise, in comparison with VCC-GRAPPA, VCC-ESPIRiT, and the original SNMs method. Impact: A VCC-SNMs method leveraging the priori knowledge of the image phase constraint was successfully implemented for efficient and robust parallel imaging reconstruction with reduced noise amplification.

• Rational Design and Dynamic Ru Exsolution Enables Active Heterostructures Surpassing Pt for Alkaline Hydrogen Evolution

  Journal of the American Chemical Society · 2025-11-24 · 4 citations

  article

  Accelerating the hydrogen evolution reaction (HER) is essential for improving water electrolysis efficiency with renewable energy, ensuring a sustainable hydrogen economy. Heterostructure catalysts show promise in significantly enhancing alkaline HER by facilitating both water dissociation and hydrogen generation, but the rational design and synthesis of robust and active heterostructures remains challenging. Here, we correlate the bias-driven dynamic surface reconstruction of ruthenate perovskites with their O 2p band center to design exsolved Ru/perovskite heterostructures for highly efficient alkaline HER. BaRuO3 is used as a model because its O 2p band center is closest to the Fermi level, allowing facile surface reconstruction under HER conditions. This results in exsolved Ru on BaRuO3 with rich oxygen vacancies, as confirmed by microscopy and spectroscopy, including in situ Ru exsolution over time under transmission electron microscopy observation. The target heterostructure shows approximately 120-fold enhancement in HER activity after surface reconstruction, with a mass activity of ∼ 1.68 times higher than commercial Pt/C at an overpotential of 80 mV. We reveal that perovskite oxides facilitate water dissociation and the exsolved Ru promotes hydrogen generation. Moreover, this bias-driven dynamic reconstruction strategy is applicable to other perovskite oxides. These findings provide guidelines for the rational design of efficient heterostructure electrocatalysts and identify the electronic structure descriptor for oxide catalyst exsolution behavior.

• Cetyltrimethylammonium Bromide/Chloride on Gold Nanocrystals Can Be Directly Replaced with Tri-Citrate

  ACS Nano · 2025-12-03 · 3 citations

  articleOpen access

  This work demonstrates an effective method for directly exchanging the toxic cetyltrimethylammonium bromide/chloride (CTAB/C) on Au nanocrystals with tri-citrate. Our experimental and computational studies indicate that counterion plays a vital role in the exchange process. Specifically, when citrate species bind to Au surface, they all evolve into tri-citrate with different counterions. In the case of three H+ counterions, tri-citrate could readily replace the CTAB/C due to a strong binding of the carboxylate group with the Au surface. The substitution of H+ counterion by Na+ or K+ weakens the binding strength and thus compromises the exchange. Additionally, our quantitative measurements and theoretical calculations indicate that Au nanospheres encased by high-index facets are advantageous over their counterparts enclosed by {111} and/or {100} facets for the exchange owing to the difference in binding strength. The mechanistic insights and experimental control should be extendable to other combinations of surface ligands and metal nanocrystals.
